USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Plant Information
(24-42 in tall x 12-16 in wide) Anise Hyssop is a summertime anchor to the garden, providing long, nectar-laden flowers that bloom from mid-summer to fall. Fragrant flowers and foliage have a scent that’s minty meets licorice-anise and will attract many pollinators. Plant with other summer bloomers such as Echinacea, Agastache, Rudbeckia, and ornamental grasses, or add it to a fragrant herb garden. Its pale purple flowers harmonize beautifully with other summer blossoms. Native to the Northwest, it is found throughout most of the US and Canada. It’s a sturdy, robust grower and will spread over time to form attractive clumps that can be divided and replanted. Plant Anise Hyssop in a sun-to-part-shade location in loamy or light clay soil that drains well. No fertilizers or amendments needed, and once established it’s a drought-tolerant, pest-resistant perennial. Good as cut flowers and as a container plant, the flowers also make dried bouquets (hang upside down in shaded spot). The fresh flowers may be sprinkled in salads and the  leaves, fresh or dried, make a delicious, soothing tea.
